Embodiment

[0036] The present invention solves the above problems. The present invention adopts the following technical solutions.

[0037] A manufacturing process for composite flooring, comprising the following steps:

[0038] S1. First, clean, dry and crush waste wood products to obtain wood powder with a diameter of less than 0.2um; then mix the obtained wood powder with water, calcium carbonate, diphenylmethane diisocyanate (MDI), polyether polyol, The mixed liquid of HQEE and HER, anti-ultraviolet light absorber UV327, nano-silica, glass fiber, antioxidant, anti-yellowing agent, iron oxide red are uniformly mixed, and then the above mixture is heated, stirred, and foamed to obtain Plastic fluid; the obtained fluid with high temperature is injected into the substrate mold with 3D bark template in the mold cavity for heating reaction; after the fluid in the mold is completely foamed and solidified, the mold cover is opened and cooled to obtain The base material with 3D bark texture ...

Embodiment 2

[0044] The difference from Example 1 is that in step S2, 27.5 parts by weight of diphenylmethane diisocyanate (MDI), 32.5 parts by weight of polyether polyol, 12.5 parts by weight of the mixed liquid of HQEE and HER, 5 parts by weight of anti-ultraviolet light absorber UV3275 parts by weight, 0.4 parts by weight of yellowing agent, 0.25 parts by weight of antifoaming agent, and 1.7 parts by weight of polytetrafluoroethylene. The temperature value during the reaction of the raw materials was controlled at 330 degrees Celsius for a reaction time of 6.25 hours.

Embodiment 3

[0046] The difference from Examples 1 and 2 is that in step S2, 30 parts by weight of diphenylmethane diisocyanate (MDI), 30 parts by weight of polyether polyol, 15 parts by weight of the mixed liquid of HQEE and HER, and 3276 parts by weight of UV absorber , 0.5 parts by weight of anti-yellowing agent, 0.3 parts by weight of defoamer, and 1.9 parts by weight of polytetrafluoroethylene. The temperature value during the raw material reaction was controlled at 330 degrees Celsius for a reaction time of 6.0 hours.

Abstract

The invention discloses a manufacturing process of a composite floor, and belongs to the technical field of composite floors. A PU hard foam base material and a TPU transparent protective layer are arranged, and the base material and the transparent protective layer are attached through the viscosity of the materials in a hot injection mode. Meanwhile, the contact area is increased by means of unevenness of the 3D bark lines arranged on the base material, the problem that the technology is tedious in the prior art is solved, and meanwhile contact is more stable. Meanwhile, the problem that the authenticity of the patterns is poor is solved in a hot injection mode.

Description

technical field [0001] The invention relates to the technical field of composite floors, in particular to a manufacturing process of composite floors. Background technique [0002] Laminate flooring is one type of flooring. However, the composite floor is artificially changed the natural structure of the floor material to achieve a floor whose physical properties meet the expected requirements. Composite flooring often refers to laminate flooring and solid wood composite flooring in the market. [0003] For example, the Chinese invention patent application document with publication number CN108797948A discloses a manufacturing process of a composite floor. It includes the processing of the panel: the processing of the surface plate, the processing of the core plate and the processing of the bottom plate; glue pressing and compounding: firstly, the core plate is coated with glue by a glue applicator, and then the billet formation and pre-pressing are carried out, and then t...
